Sep 8, 2015 - So the entire population of Ai, including men and women, was wiped out that day-12,000 in all. For Joshua kept holding out his spear until everyone who had lived in Ai was completely destroyed. Joshua (37:43)

Joshua 8:1-35

1
And Jehovah said unto Joshua, Fear not, neither be thou dismayed: take all the people of war with thee, and arise, go up to Ai; see, I have given into thy hand the king of Ai, and his people, and his city, and his land;
2
and thou shalt do to Ai and her king as thou didst unto Jericho and her king: only the spoil thereof, and the cattle thereof, shall ye take for a prey unto yourselves: set thee an ambush for the city behind it.
3
So Joshua arose, and all the people of war, to go up to Ai: and Joshua chose out thirty thousand men, the mighty men of valor, and sent them forth by night.
4
And he commanded them, saying, Behold, ye shall lie in ambush against the city, behind the city; go not very far from the city, but be ye all ready:
5
and I, and all the people that are with me, will approach unto the city. And it shall come to pass, when they come out against us, as at the first, that we will flee before them;
6
and they will come out after us, till we have drawn them away from the city; for they will say, They flee before us, as at the first: so we will flee before them;
7
and ye shall rise up from the ambush, and take possession of the city: for Jehovah your God will deliver it into your hand.
8
And it shall be, when ye have seized upon the city, that ye shall set the city on fire; according to the word of Jehovah shall ye do: see, I have commanded you.
9
And Joshua sent them forth; and they went to the ambushment, and abode between Beth-el and Ai, on the west side of Ai: but Joshua lodged that night among the people.
10
And Joshua arose up early in the morning, and mustered the people, and went up, he and the elders of Israel, before the people to Ai.
